As illustrated in FIGS. 10 to 21, the stand 10 comprises, for example,two support portions 4L and 4R, and the rotating support portion 3supported by the support portions 4L and 4R as well as rotatablysupporting the housing 2. The rotating support portion 3 is an exampleof a connection unit interposed between the support portions 4L and 4Rand the housing 2. The stand 10 may be made of, for example, a metalmaterial (e.g., aluminum alloy). The stand 10 may be formed by a casting(e.g., aluminum die casting) except for the movable portion 3 a and theattached components.

The support portion 4L is located on the left side of the display screen6 a (see FIGS. 1 and 3) in the front view. The support portion 4Lcomprises a first portion 41L and a second portion 42, which extenddownward from the cylindrical rotating support portion 3, and a linkingportion 44 extending between the first portion 41L and the secondportion 42. The first portion 41L and the second portion 42 are anexample of a standing portion.

The first portion (front support portion, front portion, first legportion) 41L has a rectangular cross-section, and extends from a baseend (upper end, end) 41La, which is connected to a front end (end) 3 bat the front from the center (center of gravity, rotating axis Ax) ofthe rotating support portion 3, toward an end (lower end) 41Lb locatedleftward, frontward, and downward in the front view (view of FIGS. 3 and12). The first portion 41L is formed in an arc shape (curved). The end41Lb is connected to an end (outer end) 44 a of the linking portion 44.For example, the first portion 41L is solid.

The second portion (back support portion, back portion, second legportion) 42 has a rectangular cross-section, and extends from a base end(upper end, second end) 42 a, which is connected to a side end (end) 3 cof the rotating support portion 3, toward an end (lower end, end) 42 blocated leftward, backward, and downward in the front view. The end 42 bis connected to an end (inner end) 44 b of the linking portion 44. Forexample, the second portion 42 is solid.

The linking portion 44 links the end 41Lb of the first portion 41L andthe end 42 b of the second portion 42, and extends along the lower edgeof the support portion 4L between them. The linking portion 44 is formedin an arc shape (curved) between the ends 44 a and 44 b. Specifically,the linking portion 44 is bent in an arc. In the embodiment, asillustrated in FIGS. 10, 11, 14, and 15, the linking portion 44 is bentto project toward a direction away from the rotating support portion 3,i.e., toward a direction away from the housing 2. As illustrated in FIG.15, a plurality of recesses 44 d are formed on a back surface 44 c ofthe linking portion 44, whereby a truss composed of triangles is formedbetween the ends 44 a and 44 b. With this truss, a structure havingrequired rigidity and strength can be achieved with a reduced weight.Instead of the truss, a honeycomb structure composed of a series of(closely-spaced) hexagons may be used. For example, the linking portion44 is solid.

The support portions 4L and 4R are symmetry with respect to a YZ plane C(see FIG. 14) passing through the center of the display screen 6 a. Thatis, the support portions 4R and 4L are in a mirror-image relation.

Specifically, the support portion 4R is located on the right side of thedisplay screen 6 a in the front view. The support portion 4R comprises afirst portion 41R and a second portion 43, which extend downward fromthe cylindrical rotating support portion 3, and a linking portion 45extending between the first portion 41R and the second portion 43.

The first portion (front support portion, front portion, first legportion) 41R has a rectangular cross-section, and extends from a baseend (upper end, second end) 41Ra, which is connected to the front end(end) 3 b at the front from the center (center of gravity, rotating axisAx) of the rotating support portion 3, toward an end (lower end, end)41Rb located rightward, frontward, and downward in the front view (viewof FIGS. 3 and 12). The first portion 41R is formed in an arc shape(curved). The end 41Rb is connected to an end (outer end) 45 a of thelinking portion 45. For example, the first portion 41R is solid.

The second portion (back support portion, back portion, second legportion) 43 has a rectangular cross-section, and extends from a base end(upper end, second end) 43 a, which is connected to the side end (end) 3c of the rotating support portion 3, toward an end (lower end, end) 43 blocated rightward, backward, and downward in the front view. The end 43b is connected to an end (inner end) 45 b of the linking portion 45. Forexample, the second portion 43 is solid.

The linking portion 45 links the end 41Rb of the first portion 41R andthe end 43 b of the second portion 43, and extends along the lower edgeof the support portion 4R between them. The linking portion 45 is formedin an arc shape (curved) between the ends 45 a and 45 b. Specifically,the linking portion 45 is bent in an arc. In the embodiment, asillustrated in FIGS. 10, 11, 14, and 15, the linking portion 45 is bentto project toward a direction away from the rotating support portion 3,i.e., toward a direction away from the housing 2. A plurality ofrecesses 45 d are formed on a back surface 45 c of the linking portion45, whereby a truss composed of triangles is formed between the ends 45a and 45 b. With this truss, a structure having required rigidity andstrength can be achieved with a reduced weight. Instead of the truss, ahoneycomb structure composed of a series of (closely-spaced) hexagonsmay be used. For example, the linking portion 45 is solid.

As illustrated in FIGS. 10, 14, and 15, in the embodiment, the firstportion 41L of the support portion 4L and the first portion 41R of thesupport portion 4R are smoothly connected (brought into contact) to eachother at a connection portion (i.e., the base ends 41La and 41Ra) to thefront end 3 b of the rotating support portion 3. For example, thetangent line at the base end 41La of the first portion 41L and thetangent line at the base end 41Ra of the first portion 41R are the same.In the embodiment, for example, the radius of curvature of the firstportion 41L and the radius of curvature of the first portion 41R areequal to each other. That is, in the embodiment, the first portion 41Land the first portion 41R form a series of an arc leg portion (front legportion, first leg portion, foot portion, arm portion, standing portion,edge portion, edge) 41.

As illustrated in FIG. 12, the leg portion 41 stands from a plane P likean arch. Specifically, the leg portion 41 is curved upward in an arcshape, wherein the ends 41Lb and 41Rb serve as lower ends and side ends,while the base ends 41La and 41Ra serve as upper ends and centerportions. In other words, as illustrated in FIG. 16, the leg portion 41extends along a plane Pc corresponding to the XY plane tilted at apredetermined angle to the X axis (the XY plane rotated counterclockwisein FIG. 16). In the embodiment, an upper surface 41 a of the leg portion41 (the first portions 41L and 41R) is along the plane Pc.

In the stand 10 having the support portions 4L and 4R configured asabove, at least four ends (first ends) 10 a, 10 b, 10 c, and 10 d becomeplacing points (contact points, support points, placing portion, placingpart, placing surface, surface) with the plane P (placing surface). Asillustrated in FIG. 5, the end 10 a as a placing point is arranged in aregion (upper-left region in FIG. 5, first position) A1 that is the leftfrontal region, in the front view, with respect to the housing 2 (withrespect to the center of gravity G of the housing 2). On the other hand,the end 10 b as a placing point is arranged in a region (lower-leftregion in FIG. 5, first position) A2 that is the right frontal region,in the front view, with respect to the housing 2 (with respect to thecenter of gravity G of the housing 2). The end 10 c as a placing pointis arranged in a region (upper-right region in FIG. 5, second position)A3 that is the left back region, in the front view, with respect to thehousing 2 (with respect to the center of gravity G of the housing 2).The end 10 d as a placing point is arranged in a region (lower-rightregion in FIG. 5, second position) A4 that is the right back region, inthe front view, with respect to the housing 2 (with respect to thecenter of gravity G of the housing 2). With this, the stand 10 can morestably support the video display device 1 including the housing 2 infront, back, left, and right directions. In the embodiment, the baseends (second ends) 41La, 41Ra, 42 a, and 43 a of the first portions 41Land 41R and the second portions 42 and 43 connected to the rotatingsupport portion 3 are an example of the second end.

In the embodiment, as illustrated in FIGS. 14 and 15, the linkingportions 44 and 45 are bent to project (protrude) toward a directionaway from the housing 2 (from the center of gravity of the housing 2).Accordingly, the stand 10 can more stably support the video displaydevice 1 including the housing 2 in the direction in which the linkingportions 44 and 45 protrude, compared to the case without the bentportion.

As illustrated in FIGS. 12 and 17, the support portion 4L comprises thelinking portion 44 extending between the first position A1 and thesecond position A3, and the first portion 41L and the second portion 42as standing portions provided with an opening (second opening) 4 asurrounded by the first portion 41L and the second portion 42 (and theupper part of the linking portion 44). When the video display device 1is placed on the plane P, the support portion 4L supports the rotatingsupport portion 3 to be apart from the plane P (to be separated from theplane P with a clearance, a gap, or a space, to be floated). The opening4 a faces the housing 2 (the bottom wall 2 h of the housing 2).

The support portion 4R comprises the linking portion 45 extendingbetween the first position A2 and the second position A4, and the firstportion 41R and the second portion 43 as standing portions provided withthe opening (second opening) 4 a surrounded by the first portion 41R andthe second portion 43 (and the upper part of the linking portion 45).When the video display device 1 is placed on the plane P, the supportportion 4R supports the rotating support portion 3 to be apart from theplane P (to be separated from the plane P with a clearance, a gap, or aspace, to be floated).

Accordingly, in the embodiment, the support portions 4L and 4R provide aspace (gap) between the rotating support portion 3 and the plane P(below the rotating support portion 3).

As illustrated in FIG. 18, even if the second portion 43 (hatchedregion) becomes nonfunctional in the stand 10 of the embodiment, the end10 d as a placing point is connected to the rotating support portion 3through the first portion 41R and the linking portion 45. As illustratedin FIG. 19, even if the first portion 41R (hatched region) becomesnonfunctional, the end 10 b as a placing point is connected to therotating support portion 3 through the second portion 43 and the linkingportion 45. FIGS. 18 and 19 illustrate the case where the first portion41R or the second portion 43 on the right side in the front view becomesnonfunctional, but the same is applied to the case where the firstportion 41L or the second portion 42 on the left side in the front viewbecomes nonfunctional.

As illustrated in FIG. 20, even if both the second portions 42 and 43(hatched regions) become nonfunctional in the stand 10 of theembodiment, the ends 10 c and 10 d as placing points are connected tothe rotating support portion 3 through the linking portions 44 and 45and the first portions 41L and 41R. As illustrated in FIG. 21, even ifboth the first portions 41L and 41R (hatched regions) becomenonfunctional, the ends 10 c and 10 d as placing points are connected tothe rotating support portion 3 through the second portions 42 and 43 andthe linking portions 44 and 45.

As described above, in the stand 10 of the embodiment, even if eitherone of the first portions 41L and 41R or either one of the secondportions 42 and 43 becomes nonfunctional, or both the first portions 41Land 41R or both the second portions 42 and 43 become nonfunctional, theplacing point does not change from the state without the nonfunctionalportion as long as the required rigidity is secured at connectionportions between the first portions 41L and 41R, the second portions 42and 43, and the linking portions 44 and 45. Thus, according to theembodiment, the stand 10 can more stably support the housing 2, i.e.,the video display device 1.

According to the embodiment, the opening 4 a is provided to the supportportions 4L and 4R, which facilitates to carry the stand 10 duringtransportation. Besides, the weight of the stand 10 can be reducedcompared to the case without the opening 4 a. Moreover, the area of anupper surface 4 c of the stand 10 can be reduced, which suppresses thereflection of light from the upper surface 4 c. Furthermore, the amountof refuses (dust, dirt, etc.) stacked (accumulated) on the stand 10 canbe reduced.

In the embodiment, as illustrated in FIGS. 3 and 12, the rotatingsupport portion 3 as a connection portion is not placed on the plane Pby the stand 10, and there is a space (region) S below the rotatingsupport portion 3. That is, the rotating support portion 3 is supportedas being apart from the plane P. Accordingly, compared to the case wherethe rotating support portion 3 is located more downward, the mass of themovable portion, including the housing 2, supported by the rotatingsupport portion 3 and a moment arm from a support point by the rotatingsupport portion 3 can be reduced. Thus, the movable portion is lesslikely to shake. The space S can be used as a place where a product or acomponent such as a remote controller, a compact disc (CD), and adigital versatile disk (DVD) is placed. Besides, the space S facilitatesto clean the space S and the surrounding area, and the backside of thehousing 2.

As illustrated in FIG. 9, the space S that is open to the front isformed with the front side of the leg portion (front leg portion, firstleg portion, foot portion, arm portion, standing portion, edge portion,edge) 41 of the support portions 4L and 4R as an opening edge.Accordingly, the back part of the stand 10 of another video displaydevice (1) can be inserted into the space S. Thus, the plurality ofvideo display devices (1) can be more closely aligned in the front-backdirection.

As illustrated in FIG. 3, preferably, the length L of the stand 10 isequal to or smaller than the width W or the height H of the housing 2.In the embodiment, the length L is smaller than the width W and theheight H. With this, not only the housing 2 but also the stand 10 caneasily be housed in a box that houses (packs) the video display device 1for transportation.

As illustrated in FIG. 17, the rotating support portion 3 as aconnection portion comprises a movable portion (rotating portion,coupling portion, engaging portion, cylindrical portion) 3 a, a fixingportion (support portion, cylindrical portion) 3 e, and a sliding member(smoothing member) 3 f. The fixing portion 3 e is provided with acylindrical housing (receiving portion) 3 g extending in the verticaldirection to house the movable portion 3 a. In the housing 3 g, there isprovided a protrusion 3 h protruding inward from the peripheral surfaceat the center in the vertical direction. The movable portion 3 acomprises an upper first member (upper member, member, divisionalmember) 3 i, and a lower second member (lower member, member, divisionalmember) 3 k connected and fixed to the first member 3 i with a fixingmember 3 j such as a screw or a hexagon head bolt. The sliding member 3f is located on the upper side, inner peripheral side, and the lowerside of the protrusion 3 h, and is interposed between the protrusion 3 hand the movable portion 3 a (the first member 3 i or the second member 3k). The sliding member 3 f is made of a synthetic resin material havinga relatively low friction coefficient. A recess (opening) such as a holeor a groove can be formed on the outer surface (sliding surface) of thesliding member 3 f. In this case, the recess functions as a retainingportion of a lubricant such as grease. The fixing portion 3 e of therotating support portion 3 is integrated with the stand 10. A mountinghole 3 m, such as a female screw hole, to which the fastener 12 passingthrough the through hole 11 d (see FIG. 8) on the attachment portion 11b of the coupling portion 11 is fastened, is formed in the upper surface(coupling surface, connection surface) of the movable portion 3 a. Themovable portion 3 a rotates about the rotating axis Ax as the centralaxis of the rotating support portion 3 within a predetermined angularrange. The fixing member 3 j is exposed to the space S, thereby thefixing member 3 j can be attached or removed (for maintenance) from thespace S.

As illustrated in FIGS. 14, 15, and 17, the two first portions 41L and41R are connected at the front of the front end 3 b of the rotatingsupport portion 3 as protruding toward the side (front) from therotating support portion 3. With this, the connection portion between aperipheral wall 3 n of the fixing portion 3 e of the rotating supportportion 3 and the leg portion 41 (the first portions 41L and 41R, thesupport portions 4L and 4R) can be widened (can be made long). Thus, thestress at the connection portion between the rotating support portion 3and the leg portion 41 (the support portions 4L and 4R) can be reduced.

As illustrated in FIG. 13, in the embodiment, fixing members (fasteningmembers) 7 and 8 to fix the video display device 1 are attached (fixed)to a back portion 3 p of the peripheral wall 3 n of the rotating supportportion 3 with the fastener 12 such as a single screw. That is, thefastener 12 is used to attach (fix) the two fixing members 7 and 8. Thefixing member 7 is a band made of, for example, a synthetic resinmaterial. The fixing member 7 is formed in a band having a constantwidth, and is provided with a plurality of through holes 7 a that mayallow a fixing member (not illustrated) such as a screw or a bandingband to pass therethrough along the longitudinal direction. The throughholes 7 a are arranged at substantially regular intervals. The fixingmember 8 comprises abase 8 a that is long in the vertical directionalong the peripheral wall 3 n, and a protrusion (standing portion,coupling portion, attachment portion) 8 b protruding from the end (end,lower end) of the base 8 a. The base 8 a is provided with an elongatedopening (slit, guide) 8 c to allow the fastener 12 to pass therethrough.The protrusion 8 b is provided with a through hole 8 d that may allow afixing member (not illustrated) such as a screw or a banding band topasses therethrough. By loosening the fastener 12, the fixing member 8moves downward, whereby the protrusion 8 b can be brought into contactwith the installment surface (installment portion, not illustrated). Theheight of the installment surface with respect to the fixing member 8may vary depending on the installment place.
